Seymour Duncan Liberator: Use as Tone Control? Add Capacitor?

    1. You can use a Liberator pot either as a tone or as a volume control, right?

    2. If using one as a tone control, how does one attach a capacitor?

    Thanks!

    I would guess you can, as they are both audio taper pots (V&T). You'll have to figure out which screw corresponds to which lug on a regular tone control. I have no experience with this solderless control.
    From the back of a regular tone control, with the lugs facing left, one lead of the cap goes to the middle terminal of the pot and the other end of the cap goes to ground. The bottom leg on the pot goes to the same wire as where your pickup wire is. If you have more than one pickup and it's a single tone control, then the bottom terminal of the pot would be connected to where your output jack is.
    You'll have to provide more information if I haven't covered it. Is your bass a V/T + V/T, or V/V+ONE Tone or what?

    Just a good-ol' P-Bass. Volume and Tone. That's it. :smug:
    What about the capacitor?

    Use a .047uf. Doesn't matter what voltage. Any 25 or 50 volt cap will work.

    Thanks.

    Actually, my question was how and where to attach the capacitor to the solderless pot.

    I guess I still have to solder the connection from the tone pot to the jack, huh? I'm planning on putting in a Switchcraft one.

    I tried visiting the SD Wiring Diagrams page, but they don't have anything so simple as a P-Bass schematic EDIT: for the Liberator Solderless system

    "I tried visiting the SD Wiring Diagrams page, but they don't have anything so simple as a P-Bass schematic".
    I thought you wanted a P-Bass schematic. I can't help you.
    Good luck.

    Yes, I'm sorry for any confusion.

    In the context of this thread, the need is for a P-Bass Schematic using the Liberator Solderless system. I was hoping that would be understood in context.

    I appreciate you taking the time to write all of that out, and it's great advice. Unfortunately, that doesn't address my question of how to do it using the Liberator system. I already own it, I've paid for it, and I want to use it.

    Maybe I'll just use this schematic, ignoring the bridge pickup and the selector switch.

    It looks like you stick one lead to the capacitor right in one of the ports and tighten the screw (no solder). That's nifty.

    That should work.
    No problem. Glad to help a fellow P-basser.
